ZZP's solution to the fragile LTG engine is here, our ZZP LTG forged long block. We start with a core engine, we then wash, bore & hone it using a torque plate (.25mm), resurface, and then add our ZZP 4340 rods, JE forged pistons, ZZP head studs, ZZP timing guides, ZZP injector spacers, and OEM rod and main bearings. We install all parts, set ring gap, and time your engine before it goes out the door. What you will receive is a freshly assembled engine that will be able to take the extra power you may want to throw at it, and be more reliable than an LTG from the factory. 

It is well known that the LTG 2.0L engine is quite weak from the factory. A variety of factors can lead to LTG's chipping pistons and "blowing up", even in stock form. While you can try to alleviate various stressors by using good quality gas (or E85) and colder spark plugs, unfortunately a blown up stock LTG is quite inevitable. Our ZZP forged rods and pistons are rated at much higher horsepower and torque levels than the factory components and can withstand the abuse from a larger than factory turbocharger like our ZFR series or our Z54/Z57 turbo. 

Our ZZP forged long block does not include an oil pan, front cover, injectors, turbo, intake manifold, starter, and various accessories like AC compressor. We highly recommend replacing your factory intake manifold after an engine failure, the intake manifold has long runners and can store pieces of engine material that could lead to a future failure even after cleaning; we offer the intake manifold here.  (We do not include an oil pan or front cover because they are specific to your drivetrain.)

How to purchase: 

Year: We offer two options for year range, 2013-2015 and 2016+. The early LTG engines have a traditional starter setup, while the 2016+ cars use a start/stop starter and the blocks are shaped differently to accommodate this. You will re-use your OEM starter on this engine. 

Camshafts: We have 4 different options for cams on our ZZP forged long block. Stock: this will include OEM intake and exhaust camshafts with our ZZP 82# valve springs & titanium retainers. 
ZZP fuel pump lobe: this will include an OEM intake camshaft and an OEM exhaust camshaft with our ZZP larger fuel pump lobe and our ZZP 82# valve springs & titanium retainers.  
Lastly ZZP Stage 2 and ZZP Stage 3; these will include our more aggressive camshafts, stage 2 lash adjusters, larger fuel pump lobe, and ZZP 82# valve springs. Read about our ZZP upgraded camshafts here.
